'GEORGE A. ARNOLD, OF MIDDLETOW-N,

CONNECTICUT, ASSIGNOR TO ARNOLD ELECTRIC COMPANY, A CORPORATON OF MASSACHUSETTS.

'VALIVE PERATING AND LOCKING @El-TICE.

Matese.

Be it known that I, GEORGE A.. ARNOLD, residing at Middletown, in the county of Middlesex and State of Connecticut, have invented certain new and useful Improvements in v`Valve Op* erating and Locking following is a specification, reference being had to the accompanying drawings, forming part thereof.

This invention has reference to improvements in -valve operating and locking devices and particularly to such devices adapted to operate and lock a slidable valve for controlling the flow of gas or air through the supply pipe of a combustion engine.

One object of thef invention is to so construct a. valve operating device -thatthe actu- `ating element therefor isconstituted by a member of a locking mechanism 'whereby the operation of the valve' and the bringing of the locking element to the locked are coincident. e

Another object of the invention is to simpli fy the construction and operation of valve position v locking devices. l

The invention consists in the valve operating element and its combination with the rotary member of alocking device.

The invention also consists in such other novel features of construction and combination-of parts as shall hereinafter be more fullv described and pointed out in the claim.

Figure 1, represents a sectional View of the improved valve operating and locking device as taken on a line 1 1 Fig. 2. Fig. 2, represents a similar view taken on line 22 Fig. 1. Fig. 3, represents a sectional view taken on line 3-3 Fig. 1 to show the stops.

As shown in the drawings, in its preferred form, 5 represents a portion of any pipe and particularl;Y lthe iuid supply pipe vadapted to communicate with the fuel supply of a combustion engine. lIntersecting said supply pipe 5 is a valve casing or chamber havin the members 6, 7 and S. Member 6 has the opening 9 embraced by the lip 10 adapted to receive one of the pipe members 5.l Member 7 is an open spacing member the opening 11 of which is of somewhat greater diameter Specification of Letters Patent.

'S has the opening 12 embracediby the lip 13, to receive the second. pipemember. f5, `and has at its under side the circular bearing .'14 having the stop shoulder 15.

In the opening 11 of member 7 is slidable the val've 16 having the perforated tongue 17 which is engaged with the pin 13 of the crank disk 19 which latter is rotatable in bearingfla of member S'and has the quadrant shoulder 20 adapted' to b'e intercepted bythe stop shoulder 15 to limit the rotative movement of this crank disk 19. This crank disk 19 has the shaft 21 which is journaled in a bearing of the member S and has the pinion 22. Mounted on the member 8 is the frame'23 having the bearing 2i, to receive the end of shaft 2l, thepinion compartment 25 and the lock receiving bore 2G which communicates with the compartment 25 by the bearing 27. In this bearing 27 is journaled the shaft 23 having at one end the slot 29 and at the other lend the pinion 30 which is engagedwith the pinion 22.

e e Vitliin the bore26 of frame 23 is located the lock member 31 of any well known lock of theYale type furnished at its inner end with the stop pins 32, 32. Rotatable in the lock member 31 is the key barrel 33 adapted to vbe rotated by the'key A and having at its inner end the extension 34: furnished ,with .the stop arm 35, which has a limited movement between pins 32, 32, and the projection 3G which is adapted to be engaged with the slot 29 ofshaft 28'. y v

By the use of the extension 34 and its projection 36'the rotatable member or barrel 33 of the lock is positively 28 through which the valve operating mechanism can be actuated.' It is of course evident that the parts28 and 34 may be lengthened if it isdesired to place farther from the valve mechanism than as shown in the drawings.

The operation-of the device will be readily l connected with shaft A isV in place in the lock the'lock member 31 pipe 5 as thecase may be. fte'r such operation key A may be removed and the valve is locked. against unauthorized operation.

l Having thus described 1my invention I shaft furnished with ya pinioirn'a,f1-annel 'y monnted on Said valve casing andlhaving Ia' plnlon compartment to receive' said pinion, a bearing for said shaft, land abeaiuig and bore at righftanglesto'ysaid .,Slhaft,I 'a shaft j ournaled, in Saii latter bealving` and having a pinion engaged Kwith ',the pinion of said first shaft, and a lock locatedin lsaid frame here and havinga key-operated'member operatively connected vvith said eecond Shaft.
